Newport Beach, CA - Numerical Control Computer Sciences has announced the inclusion of the Turbomachinery Applications Library (TAL) with their NCL version 9.1 Multi-axis machining software. The TAL contains pre-defined methods for creating 4 and 5-axis tool paths to manufacture complex impellers, blisks, and airfoils.
NCL is a powerful Computer-Aided Manufacturing software package which generates simultaneous 2 through 5-axis NC tool paths and provides parametric 3D modeling. All geometric modeling and tool path functions are fully associative. A change to the model results in an immediate change to corresponding tool paths.

The following special features are included with the TAL:

• Analysis: Provides analysis tools which check the distance blade surfaces for the purpose of determining cutter sizes and depths of cut.
• Rough machining: Effectively removes material between blade surfaces, using multiple tools if necessary, and provides for user-controlled depth of cut and stepover.
• Hub machining: Machines the hub surface leaving a user-controlled scallop height while avoiding the adjacent blade surfaces.
• Finish machining: Supports 5-axis flank milling of ruled blades or point milling of non-ruled blades.
• Leading/trailing edge machining: Provides a method for the point milling of leading and trailing edge radii surfaces.

• Rough machining: Provides the ability for 4 or 5-axis machining of the pressure and suction surfaces using a bull-nose end mill, with the cutter tilted forward in the direction of the cut. Provides gouge checking to avoid cutter/surface interference.
• Finish machining: Provides the ability for 4 or 5-axis finish machining, with user controlled scallop height, of the suction, pressure, leading and trailing edge surfaces using a bull-nosed cutter. High-speed spiral motion, where the cutter never leaves the material, is supported, in addition to standard lace and box style motion.
• Root and tip machining: Provides techniques for detail milling operations of the root and tip geometry.
